“Waylon Jennings was an American archetype, the bad guy with the big heart. When I introduced him to Muhammad Ali, they were like two little kids delighted with each other. What they had in common was being so openhearted to everyone. Over the years, I got to work by his side and be his friend and hear him say some of the funniest lines I’ve ever heard. Right now he’s probably whispering in Johnny Cash’s ear, ‘See, I told you I was sicker than you.’” —Kris Kristofferson
